Air Bag deployment
Does anyone know the criteria for the computer to deploy the airbag during a collision in terms of vehicle speed, pressure on the bumper and any other factors. We had a vehicle with substantial damage to the front bumper and the airbag did not trigger. Wondering if it is defective or impact was not hard enough? What controls the trigger for this?

There are many factors:

Speed doesn't dictate it but how quickly the impact is and how fast the vehicle stops/changes direction will be more important that speed and amount of damage.

1. Speed?
2. angle of impact.
3. location of damage.
Normally damage to the front bumper only will not activate the air bags. Owners manual says:
The driver and front passenger airbags will
deploy during significant frontal and near
frontal crashes.
If all you have to replace is the front bumper, it's all good.

Probably would not have changed the outcome. Had some whiplash but ended up with more injuries on my legs than anything. I don't think the airbag would have changed anything. The truck was a total loss after the event.

If it hit a guard rail first, it is designed not to inflate. The angle makes a difference. A guard rail can make the damage look bad. If you were going 60 and slid on a guardrail for a minute, airbags won't go off. Side curtains might though.
